Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of straightening machines for door and window processing, and in particular to a straightening machine for aluminum-plastic door and window processing. Background Technology
[0002] Aluminum-plastic composite doors and windows are actually a general term for modern door and window products. As the name suggests, they can be understood as aluminum alloy doors and windows and U-PVC plastic steel doors and windows, or aluminum-plastic composite doors and windows, such as thermally broken aluminum doors and windows, aluminum-clad wood doors and windows, and other high-end energy-saving products. During the processing and manufacturing of aluminum-plastic doors and windows, the aluminum-plastic door and window components need to be straightened before use.
[0003] A search revealed Chinese patent CN221064205U, which discloses a straightening machine for processing aluminum-plastic doors and windows. The machine includes a main structure comprising: a base plate; a first straightening component disposed on one side of the top of the base plate; and a second straightening component disposed on the other side of the top of the base plate. The first straightening component includes a side plate disposed on one side of the top of the base plate; a first baffle disposed on the top of the side plate; a fixed seat disposed on one side of the top of the base plate; a first hydraulic cylinder disposed on the top of the fixed seat; and a second baffle disposed on one side of the first hydraulic cylinder. The first hydraulic cylinder drives the second baffle to push it until the aluminum-plastic door / window is flush with the first baffle, thus improving straightening efficiency. Simultaneously, the second hydraulic cylinder drives a limiting plate at the bottom of the fixed plate to move downwards to the top of the first baffle for limiting and fixing, preventing the aluminum-plastic door / window components from warping during straightening and causing straightening failure.
[0004] The aforementioned technologies rely solely on simple downward pressure for correction, lacking vibratory hammering functionality. When simply pressing down, the corrective force is concentrated instantaneously and operates in a single manner, making it difficult to address the complex deformations (such as corner warping and localized dents) caused by uneven stress distribution in aluminum-plastic door frames. This can easily lead to incomplete correction or excessive pressure causing frame cracking, especially for frames made of brittle materials or with significant deformation, where concentrated force can easily cause secondary damage. Furthermore, the lack of sustained vibratory hammering force prevents the release of internal stress through high-frequency, low-amplitude impacts, resulting in a tendency for the corrected frame to spring back, affecting processing accuracy and stability. Utility Model Content
[0005] The purpose of this invention is to provide a straightening machine for aluminum-plastic door and window processing. This machine solves the problems of the aforementioned technologies that rely solely on simple downward pressure for straightening, lacking a vibratory hammering function. When simply pressing down, the straightening force is concentrated instantaneously and operates in a single manner, making it difficult to handle complex deformations (such as corner warping and localized dents) caused by uneven stress distribution in aluminum-plastic door frames. This easily leads to incomplete straightening or excessive pressure causing door frame cracking, especially for door frames with brittle materials or significant deformation, where concentrated force can easily cause secondary damage. Furthermore, the lack of sustained vibratory hammering force prevents the release of internal stress through high-frequency, low-amplitude impacts, resulting in springback after straightening and affecting processing accuracy and stability.

This allows for precise adaptation to the straightening needs of different areas of the door frame, enabling targeted treatment of both edge warping and overall deformation. This effectively improves the comprehensiveness and applicability of the straightening process, meeting the needs of diverse aluminum-plastic door and window processing scenarios.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0018] Please see Figure 1 - Figure 4 This embodiment provides a straightening machine for aluminum-plastic door and window processing that facilitates efficient straightening. The specific concept is as follows: A straightening machine for processing aluminum-plastic doors and windows includes a mounting base 1. The portable measuring ruler for silver mine surveying engineering also includes a pressure member and a pressure plate 2.
[0019] The lower pressure plate 2 is positioned above the mounting base 1 and is used to straighten the doors and windows.
[0020] The pressing component is located on one side of the mounting base 1. The pressing component can drive the pressing plate 2 to vibrate and press down in the vertical direction. The hammering and pressing effects can effectively correct the doors and windows.
[0021] As some examples, in this embodiment, the pressing member includes: The mounting bracket 201, which serves to fix the device, is fixedly connected to the upper surface of the mounting base 1.
[0022] The mounting box 202, which serves as the mounting unit, is fixedly connected to the inner side of the end of the mounting bracket 201.
[0023] The rotating disk 203, which serves as a connector, is rotatably connected to the inner side of the end of the mounting box 202.
[0024] It should be noted that the rotating head 204 is eccentrically connected to one side of the rotating disk 203.
[0025] The rotating arm 205, which acts as a downward pressure, is rotatably connected to the inner side of the end of the rotating head 204, and the outer side of the end of the rotating arm 205 is rotatably connected to the inner side of the end of the mounting box 202.
[0026] The connecting arm 206, which serves as a connection, is rotatably connected to the outer end of the rotating arm 205.
[0027] It should be noted that the connecting arm 206 is located on the outer end away from the rotating head 204, and the downward force is increased by lever principle.
[0028] The lower pressure rod 207, which serves as a connector, is rotatably connected to the outer side of the bottom end of the connecting arm 206, and the end of the lower pressure rod 207 is fixedly connected to the upper surface of the lower pressure plate 2.
[0029] The limiting rod 208, which serves as a limiting element, is fixedly mounted on the upper surface of the lower pressure plate 2, and the outer side of the limiting rod 208 is slidably connected to the inner side of the end of the mounting bracket 201.
[0030] The spring 209, which serves as a connector, is fixedly installed on the outer side of the end of the limiting rod 208, and the end of the spring 209 is fixedly connected to the upper surface of the mounting bracket 201.
[0031] The second motor 213, which plays a driving role, is installed on the outer side of the end of the mounting box 202, and the outer side of the main shaft of the second motor 213 is connected to the inner side of the middle part of the rotating disk 203.
[0032] It should be noted that the pressing component can drive the pressing plate 2 to move vertically, thereby causing the pressing plate 2 to vibrate and hammer continuously. The hammering action can correct the door frame, and the lever principle of the pressing component can efficiently press down. Example 2
[0033] Please see Figure 1 - Figure 4 This embodiment provides a straightening machine for processing aluminum-plastic doors and windows that facilitates adjustment of the downward pressure position. The specific idea is as follows: A straightening machine for processing aluminum-plastic doors and windows includes a mounting base 1. The portable measuring ruler for silver mine surveying engineering also includes a limit frame 210 and a first motor 211.
[0034] The limiting frame 210, which serves as a limit, is fixedly connected to the upper surface of the mounting base 1.
[0035] In addition, the bottom outer side of the mounting bracket 201 is located inside the limiting frame 210 and slides laterally inside it.
[0036] The first motor 211, which plays a driving role, is installed on the outer side of one end of the limiting frame 210. A threaded rod 212 is fixedly provided on the outer side of the main shaft of the first motor 211, and the threaded rod 212 is threadedly connected to the inner side of the end of the mounting bracket 201.
[0037] It should be noted that by displacing the lower pressure plate 2, the pressing position of the lower pressure plate 2 can be adjusted, and a correction operation can be performed on a specified position, increasing the flexibility of the device. Example 3
[0038] Please see Figure 1 - Figure 4 This embodiment provides a convenient and protective straightening machine for processing aluminum-plastic doors and windows. The specific concept is as follows: A straightening machine for aluminum-plastic door and window processing includes a mounting base 1, and the portable measuring ruler for silver mine surveying engineering also includes a protective component.
[0039] As examples, in this embodiment, the protective element includes: The protective plate 3, which serves a protective function, is positioned above the mounting base 1.
[0040] The fixing plate 301, which serves as a connector, is fixedly connected to the outer side of the end of the limiting rod 208.
[0041] It should be noted that when the pressure plate 2 is pressed down, it can drive the protective plate 3 to descend vertically and fit against the outside of the door frame to prevent the door frame from cracking and breaking.
[0042] Working principle: When using this device, the user can place the door frame that needs to be corrected on top of the mounting base 1. The user can start the second motor 213, which drives the rotating disk 203 to rotate. While the rotating disk 203 is rotating, it will drive the end of the rotating head 204 to move in a circular motion. In turn, the rotating head 204 will drive one end of the rotating arm 205 to swing continuously. While the end of the rotating arm 205 is swinging, it will drive the connecting arm 206 on the outer side of its end to move vertically. While it is moving, it will drive the lower pressure rod 207 to move vertically. The lower pressure rod 207 will move vertically, and the lower pressure plate 2 will move vertically. The door frame can be corrected by the lower pressure plate 2. The hammering can be achieved by lever principle to achieve continuous correction.
[0043] This aluminum-plastic door and window straightening machine, with its innovative transmission design and flexible adjustment function, significantly improves the accuracy and efficiency of door frame straightening. After starting the second motor 213, the rotating arm 205 swings through the linkage of the rotating disk 203 and rotating head 204, causing the connecting arm 206 and the lower pressure rod 207 to drive the lower pressure plate 2 vertically. Utilizing the lever principle, it achieves continuous hammering straightening of the door frame. Stable mechanical transmission ensures uniform and controllable straightening force, avoiding the door frame deformation or incomplete straightening problems caused by uneven force in traditional manual straightening. More importantly, the first motor 211 drives the threaded rod 212 to rotate, which in turn drives the threaded mounting bracket 201 to shift, thereby adjusting the straightening position of the lower pressure plate 2. This allows for precise adaptation to the straightening needs of different areas of the door frame, enabling targeted treatment of both corner warping and overall deformation, effectively improving the comprehensiveness and applicability of the straightening process and meeting the needs of diverse aluminum-plastic door and window processing scenarios.
[0044] The first motor 211 drives the threaded rod 212 to rotate, which in turn drives the mounting bracket 201 connected to the outer thread to move, thereby causing the lower pressure plate 2 to move and correct different positions.
[0045] When the protective plate 3 descends vertically, the fixing plate 301 drives 302 and the protective plate 3 to move down synchronously, allowing the protective plate 3 to fit tightly against the outside of the door frame to form a shield. This effectively blocks any flying debris that may occur during the straightening process, preventing safety hazards caused by door frame breakage and providing solid protection for operators. Simultaneously, this shielding design also provides auxiliary support to the edges of the door frame, reducing secondary damage caused by excessive localized stress during straightening and ensuring the structural integrity of the door frame. The dual protection of stable mechanical transmission and safety safeguards makes the straightening process smoother and safer, reducing processing losses and operational risks, and providing strong support for the efficient development of aluminum-plastic door and window processing.
[0046] At the same time, as the protective plate 3 descends vertically, it will drive 302 and the protective plate 3 to descend vertically through the fixing plate 301, so that the protective plate 3 is attached to the outside of the door frame, shielding the door frame and preventing the door frame from breaking during the downward pressure, thus increasing the safety of the device.
[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
